About Marbl
Marbl is pioneering the algorithmic flexibility trading layer to navigate the evolving electricity markets, characterized by increased volatility due to the rise of renewables, storage, and flexible demand. Our goal is to facilitate better trading decisions and execution to support a low-carbon power system. We are currently seeking a DevOps Engineer to lead our delivery infrastructure, ensuring the smooth operation of our algorithmic trading systems at scale.
About the Role
We are hiring a DevOps Engineer to design and own the delivery infrastructure that keeps our algorithmic systems running reliably at production scale.
As one of the first team members, you are joining us on a journey of building a company which makes its impact on the world by optimizing renewable assets, building forecasting engines for weather systems and energy markets, and helping to make renewable zero-emission energy sources even more competitive.
In the first year, you will be hands-on advancing our IT infrastructure, helping to set the systems up for scaling while staying performant and available, helping to build a team focused on quality, high availability, and reliable integration of our AI systems with energy markets and our partners and as the company grows you will have the choice start focusing on specific areas.
You will be deeply involved with happenings on the energy market, and exchange directly with the co-founders who have been in energy trading for decades to build the best, most efficient and low cost optimization system for renewable assets in Europe.
Tasks
- As Golang Developer: Support Development of new Backend features, including persistence and API Layer. You are building the backbone and the memory of the optimization engine, making sure that it is scalable and reliable
- As DevOps: You are automating the releases and deployment of new versions to test, staging and production servers. You maintain the gitlab-runners for CI/CD pipelines on gitlab.
- As Operations: You will decide on how to orchestrate services, when to get new instances and how to ensure that our trading systems stay operational and reliable. You maintain and expand on our infrastructure for observability and alerting using tools such as prometheus, grafana, loki.
- You are the bridge, between on one hand the researchers who want to bring the new algorithms to production, and connection to 3rd party systems, to bring the optimization results to the real world. You make sure that inference systems and optimizers run scalably, to enable customers to get fast optimization results with low latency.
